    }

   }

   public void mouseWheelMoved(MouseWheelEvent e) {
       System.out.println("" + e.getPreciseWheelRotation() +
               " - " + e.getWheelRotation());
   }

    @Override
    public void mouseClicked(MouseEvent e) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

    @Override
    public void mouseReleased(MouseEvent e) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

    @Override
    public void mouseEntered(MouseEvent e) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

    @Override
    public void mouseExited(MouseEvent e) {
        throw new UnsupportedOperationException("Not supported yet.");
    }
   

    public static void main(String[] args) {
        
        SwingUtilities.invokeLater(()->{
                Main window = new Main();
                window.setVisible(true);
        });

    }
}

There are two ways of controlling whether extra mouse buttons are enabled or not. 

java -Dsun.awt.enableExtraMouseButtons=false ApplicationDriver
System.setProperty("sun.awt.enableExtraMouseButtons", "true");
